播种方式对费乌瑞它马铃薯生长与产量品质的影响

Effect on growth,yield and quality of potato cv. Favorita with different sowing methods

试验通过改变马铃薯种薯播种方式(芽眼朝向),研究其对南方冬作区费乌瑞它马铃薯生长、产量与品质的影响。结果表明,播种深度10 cm,以芽眼朝下方式播种马铃薯,收获的马铃薯产量与商品薯率(667 m22150.66 kg,90.59%)均比芽眼朝上(667 m2 2 001.95 kg,80.44%)播种方式高,并且植株长势健壮,青薯率低。南方地区适合运用种薯芽眼朝下播种方式进行马铃薯种植。

Potato seeds were sowed by two different ways,buds downwards and the buds upwards,in order to study the influence of different seeding methods of potato cv.Favorita on growth,yield and quality in Hunan area.The results showed that potato seed buds downwards and sowing to 10 cm deep were suited for developing in Hunan areas.And the plants of buds facing down were stronger than that of the buds upwards.Higher yield（2150.66 kg on 667 m2） and higher percentage of marketable potatoes（90.59%） were achieved when planted with buds downwards as compared with buds of seed piece planted upwards,which were 2001.95 kg on 667 m2 and 80.44 %,respectively.Besides,the percentage of greening potatoes was lower in the first case due to deep tuberizaiton in soil.These results suggested that buds of seed piece should be planted downwards for potato production in southern parts of China.
